Driver core merge for 3.7-rc1

Here is the big driver core update for 3.7-rc1.
 
 A number of firmware_class.c updates (as you saw a month or so ago), and
 some hyper-v updates and some printk fixes as well.  All patches that
 are outside of the drivers/base area have been acked by the respective
 maintainers, and have all been in the linux-next tree for a while.
